About the Airtac SAI63 Standard Cylinder SAI63BX700
The AirTAC SAI63X700 is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and 700mm stroke. It provides a robust 1559 N of push force at 0.5 MPa, making it well-suited for long-travel material handling and heavy positioning tasks.
Built with a SUS304 stainless steel piston rod, this variant offers superior corrosion resistance for demanding environments. The barrel incorporates dual sensor grooves for CMSE or DMSE switches, though a magnet option (-S) is required for their use.

Where the Airtac SAI63 Standard Cylinder SAI63BX700 Is Used
Long-Travel Conveying
Ideal for pushing products or diverting gates across extended 700mm distances on automated packaging lines.
Heavy Component Positioning
Provides the 1559 N thrust needed to shift heavy machining fixtures or tooling bases along extended travel paths.
Pallet Handling
Handles the robust actuation required for lifting or indexing heavy pallets in distribution centers.
Is the Airtac SAI63 Standard Cylinder SAI63BX700 the Right Cylinder?
At 0.5 MPa, this 63mm bore yields 1559 N push and 1402 N pull force. If your application requires less force, stepping down to the 50mm bore yields 982 N, while moving up to the 80mm bore provides 2513 N for heavier payloads.
With a 700mm stroke, the unsupported rod is highly susceptible to bending under side loads. Employ an external guide rail or a fully guided cylinder to prevent rod-bearing wear. Note that standard SAI cylinders drift upon air loss; for position holding without live pressure, specify the SAIL lock or BSAI clamp-lock variant. This model features PT tapered ports and is dimensionally interchangeable per ISO 15552.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
